我有一个包含GLSurfaceView的Activity。当我按下后退按钮去上一个Activity时，它设法显示该Activity，但屏幕没有响应，最终会出现ANR。
这是onSurfaceCreated（）代码：
- 编辑 -
如果我将mSurfaceView.onPause();移动到所有者片段的onPause()，那么应用程序在退出片段后不会冻结，但它通常会无声地崩溃（没有力量）在退出片段后几秒钟。
@Override
public void onSurfaceCreated(GL10 gl, EGLConfig config) {
if (mOpenGlesVersion == OPENGLES_VERSION_10) mOpenGles = new OpenGles10();
else if (mOpenGlesVersion == OPENGLES_VERSION_11) mOpenGles = new OpenGles11();
else if (mOpenGlesVersion == OPENGLES_VERSION_20) mOpenGles = new OpenGles20();
// Let the caller know the surface has been created.
if (mListener != null) mListener.onGLSurfaceViewCreated();
// No intention of drawing anything, just gathering info.
mSurfaceView.onPause();
}
这是从/data/anr/traces.txt获取的日志信息： （由于--MORE - 有两行被弄乱了）

您的Graphics.onSurfaceCreated()已调用GLSurfaceView.onPause()。你不应该调用onPause或者你遇到死锁。 onPause()将调用wait()，您的surfaceDestroyed()将调用wait()。
